Rich 'Dutch' Morgan

Bass and backing vocals
Richards involvement with music started at an early age primarily playing brass becoming an accomplished tuba player, later (largely due to a spelling error) switched from brass to bass adding double bass and bass guitar to his arsenal so that he could provide the "deep end" for just about any situation. Having spent many years playing a myriad of styles ranging from rock to orchestral, including a long term engagement with a reputable big band gigging throughout the UK and Europe settled into Blind Lemon in 1993.
 
Drawing on a wide range of musical influences Richard honed his fusion of rock and funk styles with the added musicality drawn from his big band and orchestral experience to provide the backbone of any rhythm section.

Or maybe he just stands at the back and plays bass?
